if it helps, I found a number on my original paint black cowl induction hood, over on the drivers side hinge area on the edge of the hood. its on the side lip. my car is a 6A car and the number on the hood was 20. I can see how this could get covered during a repaint. If you ask me, if you have a numbered hood that has some week number relevance not too far off the week the car was built, it would be my 2 cents its original to the car. for me if my car was built on the 22-23rd week of the year, and the hood has a 20 on it, my guess 20 stands for the week the hood was made (speculation on my part).bob

Thanks, before I started to rip off the hood insulation on my car I thought I would ask first. I see that my cars hood had hood pins at some time and were welded and filled later on. The third owner said it had pins when he owned it and that was in the late 80's to early 90's SO???. I will check tonight my car is a 08C car build actually built 8th 9th or 10th of August 1969, 08B was skipped.

Sorry to hijack the thread but my 69 Z/28 is also a 08C. Is it really true they skipped 08B?

08B was skipped!! Johnz and Kurt and a few others on the site informed me of this. You can find out aprox what day of the month your car was built by taking the last six numbers of the vin and place them in the slot. In Jerry's book he has a break down of what number cars were built in each month and I think the list is on this site as well. They built a certain number of cars each 24 hour shift so you can break the numbers down ti find out what day your car was built.

Also in August is when they had to last minute extend the 1969 production due to the cancel of the new 1970 Camaro so check your car to see if some parts have older dates then the norm. My motor is a May 30th build with may 26th castings date on the block putting a 2 month span where the norm is 1 to 4 weeks. My heads are casting date May 27th. let me know what you find I did a tom of research and recently found my pastial vin stampings by the oil filter and posted the pics my last six are 672077

Thanks, sorry to dig this back but I just stumbled back on to the thread.

My 08C Z/28 is just 219 units before yours and also has a wide spread on the block. It was assembled on June 4th and has V0604DZ on the pad. It also has the partial vin by the oil filter that matches the car. the casting date is E16 9, as were the heads if I remember right.

My ZL2 hood is stamped "18", which would be the 18th week in 1969, or April 27 - May 3, based on the link KurtS provided covering sheet metal stamping and date codes. My Z28 is a Norwood 05A build car, so the hood predates my car build date by one week. The code is hard to see and I had to use magnifying glass to confirm the code as an 18 rather than 13.

KurtS,

Should we start a hood date code vs. car build date list similar to the data base started on the gas tank date code vs. the car’s build date? I would be curious to see how this tracks, unless sheet metal is typically dated very close to the build date of the car.

Kurt, not all GM sheetmetal has the stamps. I have some NOS 67 & 68 fenders that do not have any stampings on them. Seen many hoods w/o them also, and I use the the rear corners to identify whether they are GM or repro. If they ever change the repro corners to match the GM stuff then it is going to be pretty hard to distinguish which is which.....................RatPack.......................

Only (1 in 24) ,69 Camaros had cowl hoods. I don't believe it was often ,that an original cowl hood , (Week stamped) left its original car, and wound up on another. Most cowl hoods added to cars , were from (over the counter)...A survey would probably show, that most (Week stamped ) hoods , are close to the build date!...DON

Actually those that do have stamps are usually just like assy line pcs, but the majority of the OEM NOS stuff does not have stamps or markings of anykind. I have found that early replacement parts are usually the ones that have a stamping of some sort on them and is usually not visible once installed. Recent puchases of NOS fenders, hoods, 1/4 panels, and even tailpanels have no markings. Found one header panel that did have a stamping of 12, but that is about it. I wish there were stampings on all GM sheetmetal to help identify them as to being OEM. Repro parts with GM stickers are starting to show up more and more at swap meets and on the internet for sale. Unless you know what to look for it will be next to impossible to figure out whether you bought GM or repro parts............RatPack...................

It will be interesting to determine if we can authenticate if the hoods on our cars are original to our cars, similar to date codes on the rear quarter panels, etc. That is the reason I recommend we generate a list of body build dates vs. hood stamp dates to evaluate trends like we did on gas tanks. Those with survivor cars can be significant contributors. However, Kurt does mention a good point that, unlike gas tanks, hoods are easily replaced, so correlation between car and hood could be messy.

Question: I assume (based on the updated CRG Research Report, “The First-Generation Camaro Assembly Process”), that the cowl induction hoods were stamped and manufactured my Fisher Body then shipped over to the Chevrolet Assembly Plant, with the rest of the front end sheet metal?

Nope. The front end sheet metal forward of the firewall (hood, inner and outer fenders, header panel, fender extensions, front valance panel, radiator support, hood latch support, fender braces, etc.) was manufactured by Chevrolet, and was painted and installed on the Chevrolet side of the plants. The cowl vent grille was supplied by Fisher Body - everything else was from Chevrolet.
